This is an example of the 1936 pattern Royal Air Force service coat. This particular coat was worn by an unknown member of one of the American Eagle Squadrons. Before the United States entered World War II, many Americans volunteered for service in the Royal Air Force (RAF) and Royal Canadian Air Force (RCAF). About 15,000 Americans served in British and Canadian units, but the core of 244 American pilots served in the RAF’s 71, 121, and 133 Squadrons, which came to be known as the Eagle Squadrons.
The Eagle Squadrons were officially disbanded from the Royal Air Force on September 29, 1942. The 71, 121, and 133 Squadrons were incorporated into the U.S. Army Air Forces’ Fourth Fighter Group as the 334th, 335th, and 336th Fighter Squadrons.
